Medical imaging

exposure occurring is due to the gas radon that comes from the earth's crust and is also present in the air we breathe. When it comes to man-made radiation, one common example is nuclear weapons. However, most of the man-made radiation comes from medical procedures. This is primarily from x-rays. There are several types of personal protective equipment used in radiography. During x-rays radiation exposure can be very dangerous to the human body. PPE is always necessary to prevent…

ultrasound image with the largest (true) diameter; and thus a guarantee that the far wall intima–media thickness will be correctly measured (90_ angle between ultrasound array and arterial wall). A poorly visualized near wall may indicate a non-optimal imaging view. Furthermore the leading edge of the near wall intima–lumen interface is used when measuring lumen diameter (see below and Fig. 4). The leading edge echo from the lumen–intima interface and from the media–adventitia interface of the…

Lasik is a medical procedure that uses laser technology to correct eye problems such as hyperopia, myopia and astigmatism. Doctors perform Lasik to reshape the cornea to improve vision sharpness and clarity. Majority of eye hospitals offer Lasik in Delaware, but the experience and qualification of the ophthalmologist performing the surgery is very important. Therefore, do a thorough background check on your chosen ophthalmologist and the clinic where the surgery is going to be performed. Opt for…

general than rule-based segmentation methods []. The segmentation in pixel classification-based method is based on the feature vector for each pixel in the input image and the intensities of the lung region. Deformable models are used in medical image segmentation due to its shape flexibility. Active Shape Models (ASM) and Active Appearance Models (AAM) have been applied to segment the lung region. Although Active Shape Models and Active Appearance Model approach have become popular for…

In my first semester of college, I have been exposed to so much and I have learned so much. Learning Basic Medical Science has allowed me to learn a variety of new things that I had never even heard of before or done before like immunohistochemistry, solving case studies, and T1/T2 translational research. Immunohistochemistry was really interesting and complex. At first, I overlooked it because I thought it was my over my head and not applicable to me at the moment. Then, over time I noticed…

1. What were the main findings of Mr. Penzey’s physical exam? How could his CT results be related to his blood pressure findings? When Mr. Penzey's case study was analyzed, the initial tests performed on him indicated multiple findings. A mass was found during the CT scan, located on the adrenal gland; the adrenal gland is located on top of the kidneys, their function is to help in burning proteins and fats. This is how the adrenal gland keeps the blood pressure under control and regulates…

In 1997 Adrian Raine conducted a study that focused on brain abnormalities in murderers that were shown by the use of positron emission tomography (PET). “The aim of his experiment was to see if murderers who pleaded not guilty by the reason of insanity (NGRI) showed signs of brain abnormalities with PET scans. Raine used 41 participants, 39 of which were male and 2 of which were females. The prisoner’s reasons for insanity varied. Six said they were schizophrenic, 23 said it was due to a head…

From the second grade I thought I wanted to be a Veterinarian when I grew up. Of course no one would expect a second grader to know such details, but as I went through high school my mind never strayed away from my future goal. Senior year I got the opportunity to intern at Big Goose Veterinary Clinic where I fell in love with the practice even more. I scrubbed in on surgerys, interacted with clients, and cuddled up on animals all day. It was not until I started noticing how exhausted the…

I have always had interest in science it has been my passion since childhood. I love technology and I always wanted to pursue a career in healthcare. I am fascinated with the advancement of technology used with the medical sector such as equipment used in X-ray and ultrasound. I am interested in the work radiographers do, especially the work of diagnostic radiographer does which is they use variety of equipment to diagnose and produce image of the body to treat the injuries or disease is…

Many people would assume that performing radiographic examinations is a simple task. However, this is not the case, there are multiple factors that need to be considered when a technologist is attempting to obtain adequate radiographic images. Between didactic and clinical instruction students such as myself are learning to recognize the importance of these factors. By extension, we are learning when and why adjustments to key factors are required. Accordingly, my Instructors have stressed the…
